Esim with existing and active phone number
Dear All, I am a registered T-Mobile customer with valid phone number in the US. I am using the US sim card when travel to the United States, but this time, I want to activate esim keeping the existing US phone number. Is this officially possible to activate esim with current phone number? I download the “prepaid esim” app but it looks the esim feature is dedicated ONLY for new customers. What is more, is it possible to roll back esim to the standard one or it is only one time switch so my old simcard won’t be active anymore? Looking forward to hearing the answer from you. Appreciate your help. Best,
